[Guide] How to modify yourself system.img partition

Hi
in this thread i want to explain to everyone who want to modify (debloat, add app) to your system.img partition
First is necesary to:
-backup original system.img from your phone (make a copy to your hddpc, dvd, usb stick, disketes ... etc ... lool .. joking)
-injecting root to your system.img

this steps are explained here: http://forum.xda-developers.com/g4/g...-root-t3180586

NOW: before copy and write the new rootedsystem.img image to your phone if you want to debloat or adding new app do this in your linux machine:

- mount again your new generated rootedsystem.img image

Code:

---

mount -o loop,rw -t ext4 rootedsystem.img operatingtable/

---

now browse mounted folder (operatingtable) and delete what you want from app or app-priv folder
if you want to delete startup phone sound delete from /media/audio/ui poweron.ogg and poweroff.ogg
in same mather you can add new app to app or app-priv folder but is necesary to chmod folders and files like this:
for new directories: chmod 0755 operatingtable/app/app-directory
for new files: chmod 0644 operatingtable/app/app-directory/app.apk

when you finish do this

Code:

---

umount operatingtable

---

and now you can copy and write to your phone rootedsystem.img image
as explained here: http://forum.xda-developers.com/g4/g...-root-t3180586

PS: Of course this debloating could do directly from your phone after gained root with files managers ... but i think this method is easier.
PS2: If you debloated some apps (gapps ) ... Is necesary to restore factory settings because some updated apps are in /data/app folder ... or you can delete from there to.

Enjoy.
